My March 2019 GTI has the following and I didn’t spec them as extras:
- Dynamic Light Assist YES
- Emergency Assist YES
- Rear Traffic Alert NO
- Side scan NO
- Traffic Jam Assist YES
- Traffic Sign Recognition YES
I also find VWs spec list utterly bewildering. Audi’s configurator is far easier to understand. Having said that, everything is a £1000 optional extra with Audi 🤣
Your MY19 doesn't have Traffic Jam Assist, it has as standard (free) a pack consisting of;
Lane Assist
Dynamic Light Assist
Traffic Sign Recognition.
From MY19 (build week 51 onwards) the pack became standard (free) on the GTE/GTD/GTI/R, all other Golf models it's an option and costs £650.
The 'plus' pack adds Traffic Jam Assist and Side Assist, the 'plus' pack is £575 for the GTE/GTD/GTI/R.
There are two other packs available for the Golf, at £1120 and £1225, but they aren't available or applicable to the GTE/GTD/GTI/R.
